If you’ve ever wrestled a 200-pound washing machine away from the wall only to discover it’s still not level, you understand the unique frustration of appliance installation. That maddening wobble during spin cycles, the mysterious thumping at 3 AM, the premature bearing failure that voids your warranty—these aren’t just annoyances; they’re expensive symptoms of a problem that’s notoriously difficult to solve with traditional tools. Enter the game-changing world of digital bubble levels with Bluetooth connectivity, a technology that transforms your smartphone into a remote monitoring station, letting you achieve perfect washer alignment without the back-breaking contortions.
These sophisticated instruments combine micro-electromechanical systems (MEMS) sensors with wireless technology to deliver real-time leveling data to your mobile device. Unlike their analog ancestors, they don’t just tell you that something is off—they quantify exactly how much, in which direction, and continuously update as you make adjustments. For professional installers and DIY enthusiasts alike, this represents a fundamental shift from guesswork to precision engineering.

The Revolution of Remote Washer Alignment
The marriage of digital sensing and Bluetooth connectivity addresses the single biggest pain point in washing machine installation: accessibility. Modern front-load washers sit inches from the wall, often in cramped closets or stacked configurations where reading a traditional level becomes an exercise in futility.
Why Traditional Levels Fail in Modern Installations
Traditional spirit levels rely on a visual reading of a bubble in a fluid-filled vial, requiring direct line-of-sight. When your washer is wedged between a dryer and a wall, with mere inches of clearance, you’re forced to make micro-adjustments, crawl out to check the level, crawl back in to tweak the feet, and repeat ad nauseam. This iterative process introduces cumulative error and often results in “good enough” rather than optimal alignment. Moreover, traditional levels can’t capture dynamic changes—like floor deflection when the machine loads with water and laundry.
The Bluetooth Advantage for Hard-to-Reach Spaces
Bluetooth-enabled digital levels eliminate the physical tether between sensor and observer. You place the level on the washer drum or cabinet, retreat to a comfortable position, and monitor live data on your phone as you adjust each foot. The best models maintain connection through walls and across 30-50 feet, meaning you can even calibrate from another room. This isn’t merely convenient; it fundamentally improves accuracy by letting you focus on making precise adjustments rather than interpreting bubble positions while crammed into a corner.
Decoding Digital Bubble Level Technology
Understanding what makes these tools tick helps you separate marketing fluff from genuine capability. The technology stack directly impacts real-world performance, reliability, and longevity.
MEMS Sensors: The Brain Behind Digital Precision
Micro-electromechanical systems are microscopic machines etched into silicon chips. In leveling applications, they function as accelerometers that measure gravitational pull across multiple axes. When the sensor tilts, internal capacitive plates shift, creating measurable changes in electrical capacitance. High-end models use three-axis MEMS arrays that can detect pitch, roll, and yaw simultaneously, providing a complete spatial orientation picture. The key differentiator is sensor grade—industrial MEMS sensors offer temperature compensation and drift rates below 0.01° per year, while consumer-grade chips may drift significantly within months.
Understanding Bluetooth Low Energy (BLE) Protocols
Most modern digital levels utilize Bluetooth Low Energy (BLE 4.0 or higher) rather than classic Bluetooth. BLE sacrifices data throughput for dramatically reduced power consumption, enabling battery life measured in months rather than hours. Crucially, BLE maintains persistent connections with minimal energy draw, perfect for continuous monitoring during hour-long installation sessions. Look for devices advertising BLE 5.0 or 5.2—they offer improved range (up to 800 feet in open air, though 30-50 feet is realistic through walls) and better interference resistance in crowded 2.4GHz environments.
Critical Features for Washer Alignment
Not all digital levels are created equal, and washer installation demands specific capabilities that general-purpose levels may lack. Understanding these nuances prevents costly purchasing mistakes.
Accuracy Specifications: Decoding IP65 and MIL-STD Specs
Accuracy ratings like ±0.1° at 0° and ±0.2° at 90° tell only part of the story. The real question is repeatability—does the device return the same reading under identical conditions? Premium models undergo temperature cycling tests and shock testing to MIL-STD-810G standards. IP ratings matter enormously in laundry rooms where humidity and occasional water spills are inevitable. IP65 ensures dust-tight construction and protection against water jets, while IP67 offers brief submersion protection. For installers, IP65 minimum is non-negotiable.
Multi-Axis Measurement: Pitch, Roll, and Yaw Explained
While traditional levels measure single-plane tilt, three-axis digital levels capture complete orientation. For washers, pitch (front-to-back tilt) prevents water pooling and drainage issues, while roll (side-to-side) eliminates spin cycle wobble. Yaw (rotation around vertical axis) seems less critical but reveals floor twist or cabinet racking that affects long-term stability. Advanced models can lock specific axes, letting you focus on roll while ignoring minor pitch variations caused by floor slope.
Resolution vs. Repeatability: What Actually Matters
Manufacturers love touting 0.01° resolution, but this is meaningless without corresponding repeatability. A level might display tiny increments but vary by ±0.05° between measurements. For washer installation, look for repeatability specifications under ±0.05° with resolution of at least 0.1°—finer resolution than that becomes noise when dealing with adjustable feet that move in discrete increments. The sweet spot is a device that consistently resolves to 0.05° with high repeatability.
App Ecosystem and Connectivity Deep Dive
The hardware is only half the equation. The companion app’s design, stability, and feature set determine whether your digital level becomes an indispensable tool or a frustrating paperweight.
Must-Have App Features for Professional Installers
Beyond basic angle display, professional-grade apps offer data logging with timestamps, photo capture with overlay measurements, and tolerance alarms that beep when you hit target ranges. Look for customizable presets—“Front-Load Washer Standard” might alert at ±0.5° roll tolerance while “Delicate Equipment” tightens to ±0.2°. Cloud sync capabilities let you document installations for warranty purposes, and CSV export helps analyze patterns across multiple jobs. Critically, the app should work offline; laundry rooms often have poor Wi-Fi and cellular coverage.
Range Limitations and Signal Obstruction Solutions
Bluetooth signals attenuate dramatically through metal and water—both abundant in laundry rooms. A washer’s steel cabinet can create a Faraday cage effect, reducing effective range to 10-15 feet. Premium levels use external antenna designs and frequency hopping to mitigate this. If you experience dropouts, some apps offer “buffered mode” where the level stores data during disconnections and syncs upon reconnection. For extreme cases, look for models with optional external antenna extensions or repeater capabilities.
iOS, Android, and Cross-Platform Compatibility
App quality varies wildly between platforms. iOS apps generally offer more consistent performance due to Apple’s controlled ecosystem, while Android apps must accommodate hundreds of device variants. The best manufacturers maintain feature parity across platforms and update apps quarterly. Check app store ratings and recent update dates before purchasing—an app untouched for two years likely harbors compatibility issues with newer OS versions. Some levels offer web-based interfaces, eliminating platform concerns entirely.
Physical Design Elements That Impact Performance
The level’s physical construction determines how it interfaces with the washer and survives the harsh laundry environment. These details separate durable tools from disposable gadgets.
Magnet Configurations and Holding Power
Rare-earth neodymium magnets are standard, but placement matters. Dual-magnet designs with opposing poles create a stable, self-centering attachment to curved washer drums. Magnet strength measured in pull force (lbs) should exceed 15 lbs for secure mounting during vibration. Some models feature switchable magnets—powerful for installation, then reduced to prevent magnetizing stainless steel surfaces. Be wary of single-point magnet mounts; they can pivot, introducing measurement errors.
IP Ratings for Humid Laundry Environments
Laundry rooms generate constant humidity cycles and occasional direct water contact. IP65 protects against low-pressure water jets from any direction—sufficient for most scenarios. IP67’s submersion protection becomes relevant only if you drop the tool in a filled utility sink. More important than the rating itself is the gasket material; silicone o-rings outperform foam seals that degrade with chemical exposure. Check for port covers on charging ports—open USB-C ports defeat IP ratings regardless of internal sealing.
Display Types: LCD vs. E-Ink in Low Light
While you’ll primarily use the app display, the onboard display serves as a backup and quick-reference tool. Traditional LCDs wash out in bright light and require backlighting in darkness, draining battery. E-Ink displays remain perfectly readable in any lighting without power draw, but suffer from slow refresh rates. Hybrid approaches use transflective LCDs that reflect ambient light, offering the best compromise. For laundry room use, ensure the display has at least 200 nits brightness and anti-glare coating.
Power Management Strategies
Nothing halts an installation faster than a dead battery. Understanding power systems helps you choose a level that works when you need it, not just when it’s freshly charged.
Battery Chemistry: Li-Ion vs. Alkaline Trade-offs
Lithium-ion rechargeable batteries offer hundreds of cycles and consistent voltage output, but cold laundry rooms can reduce capacity by 30%. Alkaline AA batteries handle temperature swings better and are easily replaced on-site, but voltage sag as they discharge affects sensor accuracy. The hybrid approach—rechargeable Li-Ion with emergency alkaline backup—provides maximum reliability. Some premium models use supercapacitors that charge in minutes and last decades, though with lower total capacity.
Auto-Shutoff Algorithms and Wake-on-BLE
Sophisticated power management extends battery life from days to months. Look for levels with motion-activated wake (accelerometer triggers power-on when moved) and BLE advertising that lets the app reconnect without full power-up. The best devices draw less than 10µA in sleep mode. Avoid models with fixed auto-shutoff timers under 10 minutes—they’ll power down during extended adjustment sessions. Ideally, the level should stay active while the app maintains connection, sleeping only after prolonged disconnection.
Solar-Assisted and Energy Harvesting Models
Emerging models integrate photovoltaic cells that trickle-charge batteries under ambient light. While not sufficient for primary power, this can extend standby time indefinitely. More innovative designs harvest energy from the level’s own movement—each time you pick it up, a micro-generator tops off the battery. These features prove invaluable for professionals who might not use the tool daily but need it ready at a moment’s notice.
Installation Scenarios and Specialized Applications
Different washer configurations demand different leveling strategies. Understanding these scenarios helps you evaluate whether a level’s features match your specific needs.
Front-Load vs. Top-Load: Different Leveling Challenges
Front-load washers require extreme precision—±0.5° roll tolerance—to prevent door seal stress and bearing wear. The level must attach to the drum edge, not the cabinet, as cabinets can flex independently. Top-load washers are more forgiving but need precise fore-aft leveling for proper agitator function and water level sensing. Look for levels with slim profiles that fit under raised lids and curved mounting surfaces that match drum radii.
Stacked Units and Tight Clearance Solutions
Stacked washer-dryer combos often leave less than 2 inches of side clearance. Traditional levels can’t physically fit, but ultra-thin digital levels (under 0.5 inches thick) slide into these gaps. Some models use remote sensor pucks—wireless pods you place on the washer while the main unit stays outside. These pucks communicate via BLE back to your phone, completely circumventing space constraints. For these applications, range becomes paramount; verify 50+ foot connectivity through multiple walls.
Commercial vs. Residential Applications
Commercial washers in laundromats face continuous loading cycles and concrete floors that settle unevenly. Here, durability and continuous monitoring matter more than absolute precision. Levels with data logging and alarm outputs (some can trigger external buzzers when alignment drifts) help maintenance staff catch issues before they cause downtime. Residential installations prioritize ease-of-use and app-guided workflows that walk DIYers through the process step-by-step.
Calibration Protocols and Accuracy Verification
Even the best sensor drifts over time. Understanding calibration helps you maintain trust in your measurements and avoid costly callbacks.
Zero-Point Calibration Procedures
All digital levels require periodic zeroing to account for sensor drift and mounting surface imperfections. The process should be simple: place the level on a known-flat surface (a machinist’s granite surface plate is ideal, but a quality glass tabletop works), tap “calibrate,” and the device sets this as its zero reference. Premium models perform this automatically at power-on, comparing current readings to factory-stored profiles. Be suspicious of levels lacking user-accessible calibration—they’re essentially disposable when they drift.
DIY Verification Using Machinist Blocks
You can verify accuracy without expensive equipment. A set of grade B gauge blocks ($50-100) lets you create known angles. For example, stacking a 0.100" block under one end of a 10" plate creates a 0.57° angle. Check if your level reads consistently across multiple trials. Another method uses a water level (a clear tube filled with water) as an absolute reference—water always finds true level, regardless of magnetic fields or electronic interference.
When to Recalibrate Your Device
Professional installers should verify calibration monthly or after any drop from over 3 feet. Temperature extremes accelerate drift; if your level sat in a freezing truck overnight, recalibrate it after warming to room temperature. For homeowners, annual calibration suffices unless you notice inconsistent readings. Some apps track calibration history and prompt when intervals are exceeded—a feature worth its weight in gold for busy technicians.
Common Pitfalls and How to Avoid Them
Technology amplifies both competence and incompetence. Knowing these common mistakes prevents you from becoming a cautionary tale.
Over-Reliance on Technology Without Fundamentals
A digital level won’t compensate for a warped floor or a washer with uneven feet. Always start with the basics: verify the floor is structurally sound, check that all four feet contact the ground, and ensure the washer isn’t twisted in its frame. The level is a precision instrument, not a magic wand. Use it to fine-tune, not to diagnose fundamental installation flaws.
Ignoring Floor Slope and Subfloor Issues
Many laundry floors slope toward a drain—intentionally. A digital level will show this slope, tempting you to “correct” it. Don’t. Washers are designed to operate on slight slopes; completely leveling to 0.0° on a sloped floor can cause drainage problems. Instead, use the level’s relative measurement mode: zero it on the floor itself, then level the washer relative to its foundation. This maintains proper water flow while eliminating wobble.
Bluetooth Interference in Modern Homes
Your smart thermostat, baby monitor, and Wi-Fi router all compete for the 2.4GHz band. Bluetooth’s frequency-hopping helps, but dense interference can still cause dropouts. If you experience connectivity issues, temporarily disable nearby 2.4GHz devices. Some levels let you manually select channels or operate in “noisy environment” mode with reduced data rate but increased reliability. For critical installations, consider a USB Bluetooth dongle with external antenna for your phone, boosting receive sensitivity.
Maintenance and Care Best Practices
Treat your digital level like the precision instrument it is, and it’ll deliver decades of reliable service. Neglect it, and you’ll be replacing it annually.
Cleaning Protocols for Laundry Room Environments
Laundry detergent contains abrasive particles and corrosive chemicals. Wipe down your level with a damp cloth after each use, paying special attention to magnet surfaces where metal filings accumulate. For stubborn residue, use isopropyl alcohol—never acetone or harsh solvents that attack plastic housings. If the level gets soaked, remove batteries immediately and let it dry for 48 hours before powering on. Silica gel packets in your tool bag absorb ambient moisture and prevent internal condensation.
Firmware Updates and App Maintenance
Manufacturers release firmware updates to fix bugs and improve sensor algorithms. Update quarterly, but never right before a critical job—updates can introduce new issues. Read release notes carefully; some updates change calibration constants, requiring post-update zeroing. Keep the app updated, but maintain one device with a known-stable version as backup. Cloud-based apps can change features without warning; screenshot your preferred interface in case it disappears.
Storage Recommendations
Store levels away from strong magnetic fields (speaker magnets, motor housings) that can remagnetize sensors or distort calibration. Temperature-controlled environments prevent battery degradation and sensor drift. If storing long-term, remove alkaline batteries to prevent corrosion. For rechargeable models, store at 50% charge—full charge stresses cells, while deep discharge can brick them. A padded case prevents physical shock that misaligns internal sensor dies.
Troubleshooting Guide for Technicians
When things go wrong on a job site, you need solutions, not excuses. These field-proven fixes address the most common issues.
Pairing Failures and Reset Procedures
If your level won’t pair, first ensure it’s not already connected to another device—BLE devices often accept only one connection. Force-close the app on all devices, then power-cycle the level (remove battery for 10 seconds). For stubborn cases, most levels have a hardware reset: hold the power button for 10+ seconds until the LED flashes a specific pattern. Consult the manual for the exact sequence. As last resort, some models have a “factory reset” hole you press with a paperclip, clearing all paired devices and restoring default settings.
Dealing with Signal Attenuation
Metal cabinets and concrete walls kill Bluetooth signals. If you’re losing connection during adjustment, try these fixes: elevate your phone (higher antennas clear obstacles), use a USB extension cable to position a Bluetooth dongle closer to the washer, or switch to a level with external antenna capability. Some apps show real-time signal strength (RSSI); aim for values above -70dBm. If signal is marginal, reduce data update frequency in app settings—slower updates are better than no updates.
App Data Corruption Recovery
Apps can crash during logging, corrupting measurement files. Enable auto-save features that write data every 30 seconds rather than at session end. Use cloud sync as backup, but maintain local copies. If corruption occurs, some apps can repair SQLite databases using built-in tools. For critical warranty documentation, take manual photos of the level’s onboard display as immutable proof of alignment. Consider using a second phone running a different OS as a redundant data logger.
Price-to-Performance Analysis
Digital levels span from $30 consumer gadgets to $500 industrial instruments. Understanding what you get at each tier prevents overspending or buying inadequate tools.
Entry-Level Consumer Models ($30-$60)
These levels use single-axis consumer-grade MEMS sensors and basic BLE modules. Accuracy hovers around ±0.2°, sufficient for most residential washers but marginal for high-speed spin models. Apps are often ad-supported and may sell your usage data. Build quality is plastic-heavy with moderate IP ratings (IP54 typical). Battery life is 3-6 months. They’re fine for homeowners who level one washer, but professionals will find them lacking durability and precision.
Professional-Grade Features Worth Paying For ($75-$150)
This sweet spot offers three-axis industrial sensors (±0.05° accuracy), metal housings, IP65+ ratings, and professional apps with data export. Battery life extends to 12+ months, and calibration is user-accessible. Magnetic mounts are robust, and Bluetooth range reliably hits 50 feet through walls. Warranty terms stretch to 2-3 years. For appliance technicians, this range provides the best ROI—accurate enough for warranty work, durable enough for daily use.
Premium Industrial-Grade Models ($200+)
These instruments boast laboratory-grade sensors (±0.01° accuracy), MIL-STD-810G shock resistance, and advanced features like temperature-compensated readings and multi-device mesh networking. Apps include API access for integration with business management software. Battery systems are hybrid or supercapacitor-based. You’re paying for marginal gains in accuracy that most washer installations don’t require, but for commercial laundry installations or high-end appliance dealers, the documentation and reliability justify the cost.
Emerging Technologies on the Horizon
The digital leveling space is evolving rapidly. These innovations will reshape expectations within the next 2-3 years.
AI-Powered Alignment Assistance
Next-generation apps will use machine learning to analyze your adjustment patterns and predict optimal foot positions. By logging thousands of installations, AI can identify floor types (concrete, wood, tile) and recommend specific techniques. Imagine an app that says, “Based on your floor’s deflection pattern, turn the left front foot 3/4 turn and the right rear foot 1/2 turn to achieve perfect level.” Some prototypes already exist in industrial applications and are trickling down to consumer tools.
Matter Protocol Adoption and Smart Home Integration
The Matter smart home standard promises seamless interoperability. Future levels will broadcast alignment data directly to smart home hubs, triggering notifications if a washer drifts out of level during use. Integration with vibration sensors could automatically pause an unbalanced spin cycle before damage occurs. This moves leveling from a one-time installation task to continuous condition monitoring, potentially preventing failures before they happen.
Blockchain-Verified Calibration Certificates
For commercial installations where warranty compliance is legally binding, blockchain technology can create tamper-proof calibration records. Each level’s sensor data, calibration date, and technician credentials become an immutable ledger entry. Manufacturers and insurance companies could instantly verify that an installation met specifications, reducing disputes and liability. While overkill for homeowners, this could become standard for multi-family housing developments and commercial laundries.
Your Decision-Making Framework
With dozens of options available, a systematic evaluation process ensures you select the right tool rather than the most marketed one.
Creating a Requirements Matrix
List your specific needs: residential vs. commercial, frequency of use, required accuracy, typical installation environments (tight spaces, outdoor, etc.). Assign weights to each factor (accuracy might be 30% of your decision, battery life 20%, price 25%). Score each candidate level against these criteria. This objective approach prevents emotional decisions based on flashy features you’ll never use. For example, if you only install top-load washers in open basements, extreme Bluetooth range is irrelevant.
Warranty and Support Evaluation Criteria
A robust warranty tells you everything about a manufacturer’s confidence. Look for 2+ year warranties that cover sensor drift and water damage. Check support channels: is there a US-based phone number, or only email tickets? Response time matters when you’re mid-installation with a faulty tool. Some premium brands offer advance replacement—if your level fails, they overnight a replacement while you return the defective unit. Read warranty fine print; some exclude “professional use,” making them useless for contractors.
Where to Buy and What to Avoid
Purchase from authorized retailers or directly from manufacturers. Amazon and eBay are rife with counterfeit levels using cloned hardware and malware-laden apps. Check the seller’s rating and verify they’re an authorized dealer. Avoid “open box” deals—calibration could be compromised from previous drops. For professional use, establish a relationship with an industrial tool supplier who offers calibration services and bulk discounts. They’ll also alert you to recalls and firmware issues.
Frequently Asked Questions
What makes a digital level better than a traditional spirit level for washing machines?
Digital levels provide quantifiable measurements rather than subjective bubble interpretation, allow remote monitoring via Bluetooth so you can see readings while adjusting feet, capture multi-axis data simultaneously, and log measurements for warranty documentation. They eliminate the iterative crawl-check-adjust cycle that introduces errors in tight spaces.
How accurate do I really need to be when leveling a washer?
Most manufacturers specify ±0.5° for side-to-side level and ±1° front-to-back. However, high-speed spin models (1200+ RPM) benefit from tighter tolerances around ±0.3°. The key is consistency across all four feet—relative level matters more than absolute perfection. A washer perfectly level to 0.0° but with one foot slightly off will wobble more than one at 0.5° but uniformly supported.
What’s the realistic Bluetooth range in a typical laundry room?
In open air, expect 30-50 feet with BLE 5.0. Through a single drywall wall, this drops to 20-30 feet. Metal washer cabinets and concrete walls reduce range to 10-15 feet. For stacked units in closets, you may need to keep your phone within line-of-sight of the level. External antenna accessories can extend range by 50-100% in challenging environments.
Can I use the same digital level for other appliances like dryers and dishwashers?
Absolutely. The same principles apply to any appliance requiring level installation. Dryers need level for drum rotation and moisture sensor accuracy. Dishwashers require precise leveling for door sealing and proper drainage. Some apps include presets for different appliance types, automatically adjusting tolerance alarms. Just ensure the level’s magnetic mount doesn’t interfere with dishwasher electronics or scratch stainless steel finishes.
Do these levels require Wi-Fi or cellular data to work?
No. Bluetooth levels communicate directly with your phone, no internet required. However, some advanced features like cloud backup, firmware updates, and manufacturer support portals need periodic internet access. The core leveling functionality works completely offline, which is crucial in laundry rooms that often have poor signal reception.
How often should I recalibrate my digital level?
For professional installers, verify calibration monthly using a known-flat surface or gauge blocks. Recalibrate if the level is dropped from over 3 feet or exposed to extreme temperatures. Homeowners should check calibration annually or if readings seem inconsistent. Many apps track calibration dates and prompt when intervals are exceeded. Always recalibrate after firmware updates, as they can reset calibration constants.
What if my laundry room has terrible cell reception? Will that affect Bluetooth?
Cellular reception doesn’t impact Bluetooth, which uses the 2.4GHz band. However, poor cell signal often correlates with being in a basement or interior room with thick walls, which does attenuate Bluetooth. The solution is the same: stay within 10-15 feet of the level, minimize obstacles, and consider a Bluetooth range extender. Unlike cell signals, you have direct control over Bluetooth device placement.
Are digital levels waterproof enough to handle laundry room humidity?
Look for IP65 minimum rating, which protects against water jets and condensation. IP67 offers submersion protection but is overkill for most scenarios. The bigger concern is long-term humidity exposure, which can corrode internal contacts. Store the level in a sealed bag with desiccant when not in use. Avoid models with open charging ports; magnetic or wireless charging is preferable. Even waterproof levels should be dried thoroughly if they get wet before storage.
Can I use these apps on a tablet instead of a phone?
Most apps are optimized for phones but run fine on tablets, offering the advantage of larger displays for easier reading at a distance. However, some Android tablet variants have poor Bluetooth antenna placement, reducing range. iPads generally perform excellently. Check app store descriptions for tablet-specific UI mentions. Landscape mode support is crucial for tablets; some phone-centric apps only work in portrait orientation.
Why does my digital level show a different reading than my old spirit level?
First, verify both are zeroed/calibrated on the same reference surface. Spirit levels can go out of calibration if the vial shifts or the frame bends—common after years of use. Digital levels can drift or be affected by nearby magnetic fields. If discrepancies persist, trust the digital reading after confirming its calibration. Spirit levels have inherent parallax errors and surface tension effects that digital sensors don’t. However, if the difference exceeds 0.5°, test both on a machinist’s surface plate or with a water level to determine which is correct.
